Suchke, Atlanta, Ga., assignor to Pioneer Heddle and Reed Company, Incorporated, Atlanta, Ga., a corporation of Georgia Application Gctober 31, 1952, Serial No. 318,113 11 Claims. (Cl. 139--92) The present invention relates to heddle bar supports useable in heddle frames to support the heddle bars which in turn carry a plurality of heddles.

A primary object of the present invention is to provide a support or hook which will support adequately a heddle bar intermediate its ends throughout the continuous operative cycles of the heddle frame and at the same time not suffer dislodgement or displacement thus interfering with the normal operation of the loom.

Another object of the invention is the provision of a support or hook for the heddle bar so constructed and arranged that it may move longitudinally in the heddle frame and along the heddle bar with a minimum of friction and avoid pinching or twisting which would preclude free travel of the support.

A further object is the provision of a support or hook which is readily adaptable without change of its structure for use in single or duplex heddle frames.

In general, the support or hook for the heddle bar is arranged for mounting and travel upon an auxiliary bar carried in the heddle frame and comprehends a horizontal portion which embraces in part the auxiliary bar and a vertical leg which also embraces in part the auxiliary bar and the heddle bar. The structural features of the support or hook comprehends a disposition of the major area of the hook to one side of the auxiliary and heddle bars and at the same time diminishing materially the presence of sharp corners and protuberances of like character which serve to pick up and retain lint and other deleterious material.

In utilizing the support for use in standard duplex heddle frames the surfaces of greater area are preferably positioned in opposed relation with sufficient clearance between the surfaces of each support to assure -clearance in their movement or travel along the auxiliary and heddle bars. Since the likelihood of these surfaces to catch lint and other material is substantially reduced it follows that the likelihood of accumulating such material between the supports when they occupy opposing positions on their respective auxiliary bars is correspondingly reduced. The areas of the support which appear on the other or opposite sides of the bars are minor in extent and embrace those portions of the support selected to retain the support upon the auxiliary bar and to carry the heddle bar.

FIhe support is fashioned with a horizontal and vertical leg portion lying in the main on one side of the auxiliary bar and the horizontal leg adjacent its opposite ends is bent or turned at an angle so as to cross and rest upon the outer edge of the auxiliary bar thereby positioning ends of reduced area of the horizontal leg on the opposite side of the auxiliary bar. The vertical leg of the support is slotted and formed with a lug arranged to receive and embrace the inner portions of the opposite side and inner edge of the auxiliary bar. The result of this construction is the provision of a series of bearing surfaces of small area each serving to retain the support for easy sliding movement upon the auxiliary bar, the

2,739,618 Patented Mar. 27, 1956 avoidance of binding and pinching and at the same time restrain such movements of the support as would dislodge it from its correct position on the auxiliary bar. The inner portion of the vertical leg of the support is slotted in such a way as to provide an open hook for the reception and support of the heddle bar and for sliding movement along said bar.

The invention will now be described in detail, reference being had to the accompanying drawings wherein corresponding parts are identified by corresponding marks of reference and wherein- Fig. 1 is a side view partly broken away of a single heddle frame and its associated parts showing the sup port or hook for the heddle bar applied thereto.

Fig. 14 is a section on the line 14-14 of Fig. 12.

In Fig. l there is shown a single heddle frame fashioned with top and bottom wooden rails 1 and dual metallic end pieces 2, the opposite ends of which are turned at right angles and fastened to the ends of the wooden rails. Heddle bars 3 spaced from the rails 1 carry the heddles 4 and the opposite ends of the bars 3 penetrate the end pieces 2 where they are detachably secured in position by the spring clips 5, carried by the end pieces, entering openings 6 in the heddle bars. The construction just described is old and extensively used in the art.

Since the upper and lower sections of the heddle frame and the parts associated therewith are identical but assume reversed positions, it will suice to describe the invention with relation to the upper half or section of the heddle frame.

Between the wooden rail 1 and the adjacent heddle bar 3 and spaced from each of them there is positioned an auxiliary bar 7 which may extend continuously throughout the length of the frame with each of the bar carried in the end pieces. These bars may be shorter in length with their ends supported by the wooden rail 1. In any event a support or hook generally designated 8 is arranged to be movably or slidably carried by the auxiliary bar 7 to support the heddle bar 3 and in turn the heddles 4. The support 8 can be conveniently fashion as a single or integral piece by striking the same from sheet metal in the form shown in Fig. 8 and then swaging it to the desired shape. It may also be forged or castto shape with its contact surfaces machined or ground if desired.

The support comprehends a horizontal leg it) and a centrally positioned vertical leg 11 extending inwardly therefrom. When fashioned from sheet metal it is dein a small arc about its vertical center' line A-A sol as to form the vertical spaced sections 12. At the same time the horizontal leg may be swaged vertically in alignment with the center line of the vertical leg as at 13 so..-as to.- reinforce Ithe horizontalileg against deformation. 'Ihisfconstruction is-shownin;Figs. '5.-and.5. Instead of arranging the -sections 12 one. spacedv from the. other they may.ibe1brought togethe1':.as..shown in Pigs.'9.and lO and yspot welded.

The bent sections 20 of the leg in traversing the outer edge of the auxiliary bar brings the horizontal surfaces 16.into positiomtotor-mfwidely spaced bearings for the outer ends of the horizontal leg contacting with the outer edge ofl theauxiliary bar.

Each of thesectionslzof the vertical leg .11, whether spaced .apart asvshown in Figsfl, 5 and' 6 or brought together and united as.` shown inFigs. 9 and l0, is.slotted adjacent its outer end as at 21 and formed witha lug 22. Theslot 21fandlug.22 are-.shaped .and .arranged so :as :to permit the. support towernbrace vthea-auxiliary bar and slide freely thereon as shown inFig. 3 whereit-will be .observed that. the lugs 18 at the. endsof the; horizontal leg v'10'and the lugs 2210i the vertical leg sections 12. lie on the same side of the auxiliary bar with an apparent space22abetween them. The innerends .ofthe sections 12 of the vertical leg are slotted as at 23 and provided with lugs `24' to. form. an open hook to receive vthe heddle bar 3.

To prevent the distortionof the auxiliary bar, which may arise due to a bowing of the wooden rails especially inthe. case of trames. of extendedlength, Aoneor more brackets. -are employed having their outerendsvadjustably-attached to the wooden rail :1 and theirinnerends attached totheauxiliary. har 7 in the manner :about to be described.

In Figs. l2, 13 and 14 there is shown a duplex heddle frame wherein there is included two auxiliary bars 7 and two heddle bars 3, the latter held in the end pieces of the frame by spring clips. 5. Each heddle bar carries its usual set of heddles 4. Brackets 30 are mounted on the opposite faces of the rail 1 andeach .are mounted for adjustment as previously described. Eachhracket extends inwardly and is attached to the outside'face ,of'its complementary auxiliary bar in the manner-.previously Vdescribed. Each auxiliary bar carries its individual support or hook 8 in the manner- -shownin Fig. Maso-that major areas of the support .are adjacent each other and since these areas are relatively smooth and not broken or interrupted by openings, lugs, etc., the tendency to collect lint or other material on the inside of or between the hooks, where accessibilitymaytzbedifficult, is.1suhstan tially reduced.
